'.l() ALL WHOM IT MAY COIICERN:

.lle it' known that I, G. H. DOW, of Freeport, in the eountT of Stephenson, und State of Illinois, have invented certain new and useful Improvements in Churn-Dashers; and I do hereby declare tha-t the following 'is a i'ullnnil complete description of the same, reference being had to the aceompanyig drawings, making a part of this specification, in which- Figure 1 is a side view. Figure 2 is a detached section. ligu-re 3 ism -t-op view.4 'Y Figure 4'is :t view of the under side. y Like letters of referenceV refer to like parts in 'the views.

Iii the drawings, A represents a tubular shaft, and B the dasher, provided with arms B. This shaft can:

be umile either longor'sh'ort, according to the size of the churn, and can be operated by hand or any mechanicaluncans. Near each end of the arms is a hole, a, shown in figs. 2 and 3, the arms being .curved from the shaftto the ends, as shown in fig. 1. C is :t projection from the under side of the dasher, and which is conenved, as shown in fig. 4, and the dotted' line, fig. I. '.lhe holes a are also coneaved, shown in I and 4.. In the top of the shaft is placed the detachable valve-seat D, :i Vertical section of which is shown in iig. in which IY' is the valve that rests upon the support E, as represented.`

When the dasher is pushed down in churning, 'the air will i`o1-ee'the valve D up, and thus elose the opening In, und prevent the cream .from being thrown out, and as the dusher is raised the valve will open, allowing a. current of nir'topass in, and by means of the concaving openings and the projections C' in the-under side of the dasher, the cream is greatly and successfully agitated. j

What I`elaim as.A my improvement, and desire to secure by Letters Patent, is

The valve-seat D and valve D', in combination with-the dasher B and shaft A, when constructed a-s'and for the purpose set forth. v

GEORGE H. DOW.
